ALEXANDRE M. GREAN, OF NEW YORK, N. Y.

BEL-TING.

Specification of Letters Patent.

Patented Uct. 8, 1918.

Application filed October 6, 1916. Serial No. 124,096.

To all whom it may concern:

Be it known that I, ALEXANDRE M. GREAN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Belting, of which the following is a specification.

The present invention relates to belting of the character disclosed in my prior Patent No. 1,183,869, dated May 23, 191b, and

the object is to provide a simple and effective structure that is permanently shaped, can be cheaply manufactured, and is efiectively reinforced. I

Twoembodiments of the invention are disclosed in the accompanying drawings, wherein Figure '1 is a view in elevation of one form ofconstruction;

Fig. 2 is a transverse sectional view thereof.

Fig. 3 is a side elevationof another embodiment of the invention, and

Fig. 4 is a cross sectional view through the structure illustrated in Fig. 3.

Fig. 5 is a detail view showing a strip of the material when straight.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated in Figs. 1 and 2, a strip 5 of woven flexible material is employed, having longitudinal and transverse threads, or made straight as disv tinguished from on the bias, and preferably provided with transverse ribs formed in the weaving. This strip is preferably impregnated with a stiffening material and has a permanent transverse curvature. This curvature is produced by shaping the same in suitably formed dies, so that the edges are longer than the central portions.

The edges of the strip are reinforced by strips or tapes 6, which are folded over 5 said edges and are secured thereto by lines of stitching 7. A third tape-8 is also employed which is located along the central portion of the body strip 5, and is secured thereto by lines of stitching 9. These tapes not only constitute efi'ective reinforcements, but the three tapes furthermore serve to prevent stretching of the body 5.

In the embodiment disclosed in Figs. 3 and 4, a body strip o is employed similar to es the strip 5 of the embodiment illustrated in Figs. 1 and The edges of this strip 5 are reinforced by cords 6 disposed longitudmally along the same and secured in place by lines of stitching 7 that .inclose said cords. The central portion of the strip 5 isreinforced and held from stretching or extension by one or more lines-of stitching 8*, strong thread being employed for the purpose.

In connection with this invention, it will be understood that not only isthe structure provided with a permanent transverse curvature, or is so constructed that it will readily assume thesame and fit the object to which it is applied, but the margins are stretched or made longer than the intermediate part. The preferred method of making the belting is as follows 2-- A straight strip of material is employed, and the intermediate tape 8 of Fig. 1 or a line ofstitching of strong thread as 8 of Fig. 2 is secured. thereto. The material with this tape is then pressed between dies, one of which is a round block having a hollow or transversely curved surface and the coacting die having a reversely shaped mating surface. These dies are preferably heated, though cold dies may be employed if less curvature is desired. After it is thus shaped, the edges are bound with the tape, which will prevent further stretching, or cord, as shown in Figs. 3 and 4, may be employed as a reinforcement, this' cord, being also substantially incapable of being stretched.

It is possible to shape or press the material after the marginal tapes or cords are thereon, but in such cases, it is necessary to use more powerful presses and to moisten the material more thoroughly. 1

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and. it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As an article of manufacture, a length of belting comprising a strip of flexible woven material having transverse and longitudinal threads. means of less width than the strip and extending along the edges of said strip for reinforcing the same, and means along the intermediate portion of the strip for reinforcing said strip and preventing said portion from being longitudinally stretched.

2. As an article of manufacture, a length of belting comprising a strip of flexible material permanently shaped to have a transverse curvature, means of less width than the strip and extending along the edges of said strip for reinforcing the same, and means along the intermediate portion of the strip for preventing the stretching thereof.

3. As an article of manufacture, a length of belting comprising a strip of flexible material permanently shaped to have a transverse curvature, a binding covering the longitudinal edges of the strip and including reinforcing elements extending longitudinally along said edges, and of less Width than the strip and means secured l0ngitudinally along and to the intermediate portion of the strip for preventing stretching thereof.

4. As an article of manufacture, a length of belting comprising a strip of flexible Woven material permanently shaped to have a transverse curvature, separate binding tapes covering the longitudinal edges of the strip and secured thereto, and constituting reinforcements for the belting, a central tape extending longitudinally along the strip, and means for securing said tape to said strip, said central tape also constituting a reinforcement for the belting and preventing the stretching of the central portion thereof.

5. As an article of manufacture, a length of belting comprising a strip of flexible woven material having transverse and longitudinal threads, separate means along the edges of the strip and of less Width than the same for reinforcing said strip, and means along the intermediate portion of the strip for reinforcing said strip and preventing said portion from being longitudinally stretched, said strip being permanently shaped to have a transverse curvature and having its marginal portions longer than its intermediate portion.

6'. As an article of manufacture, a length of belting, comprising a strip of flexible material having longitudinal and transverse threads disposed straight as distinguished from the bias, said strip being shaped to have a transverse curvature and having its longitudinal edges. longer than its central portion, separate means secured longitudinally along its intermediate portion and means along its edges to reinforce the same and prevent stretching thereof.

In testimony whereof I aflix my signature in the presence of tWo Witnesses.
